Sometimes
after editing a family you will not able to load a family. Revit gives an error as shown below:

An
error occurred in family "XXXXX.rfa" that cannot be automatically
resolved.Error Information:"Last type in system family 'Stacked Wall' cannot be deleted."

After this error the user needs to
cancel a reload.

I looked for journal files, it gives
me below:

< DBG_WARN: Family contains
category id -2009633, gstyle type 2, gstyle id 483342. That category id
and gstyle type map to a gstyle id of invalidElementId in the project.
(In practice, this is most commonly caused by a mismatch between the version
number passed to addNewGStyles and the version number in the table in
ProjectStyles.cpp, due to an incomplete renumbering of an upgrade.

So as per this I
searched for id 483342 element. Surprisingly in my titleblock family it's
showing this ID for Analytical Braces. I selected it and deleted this blank
element. Afterwards I tried for Purge and auditing a family. But still
facing same issue
